Description

Technical Field

[0001] The utility model relates to a mixer, in particular to a material mixer for brick production and processing. Background Art

[0002] At present, the Chinese patent with the announcement number CN209615961U discloses a concrete mixer, including a mixing box, a motor arranged at the bottom of the mixing box, and a stirring device arranged inside the mixing box, wherein the stirring device includes a stirring shaft connected to the output end of the motor, a stirring blade arranged at the upper end of the stirring shaft, and a scraper arranged at the bottom of the stirring blade. When in use, the material to be mixed is placed in the mixing box, and the stirring shaft is driven by the motor to rotate in the circumferential direction. At the same time, the stirring shaft will stir the material through the stirring blade and the scraper, so that the materials are mixed with each other. However, when using the above-mentioned mixer to stir the materials for brick firing, part of the material will adhere to the surface of the mixing box, affecting the utilization rate of the material. Summary of the Invention

[0003] In view of this, the purpose of the present invention is to provide a material mixer for brick production and processing, which has the advantage of higher material utilization rate.

[0004] In order to solve the above technical problems, the technical solution of the utility model is: a material mixer for brick production and processing, comprising a mixing box, a mixing motor arranged at the lower end of the mixing box, and a mixing mechanism arranged inside the mixing box, the mixing mechanism comprising a mixing shaft rotatably arranged at the center position of the mixing box, and a mixing blade arranged at the side wall of the upper end of the mixing shaft. The upper end of the mixing box is rotatably connected to a movable ring, and the central axis of the movable ring coincides with the central axis of the mixing box. A number of scrapers are arranged on the inner side of the movable ring, and the scrapers are evenly distributed along the circumference of the movable ring. The outer side wall of the scraper is tightly pressed against the inner side wall of the mixing box. A power mechanism is arranged on the outer side of the upper end of the mixing box, and the output end of the power mechanism is connected to the movable ring to drive the movable ring to rotate circumferentially.

[0005] According to the above technical solution, when in use, the brick-making materials are placed into the inner side of the mixing box through the top opening of the mixing box, and the stirring shaft is driven by the stirring motor to rotate circumferentially, and the stirring shaft drives the stirring blades to rotate to stir the materials. At the same time, the movable ring is driven by the power unit to rotate circumferentially, and the movable ring drives the scraper to rotate. Since the scraper collides with the inner wall of the mixing box, the material attached to the inner wall of the mixing box can be scraped off when the scraper moves, so that it falls back to the inside of the mixing box and participates in the stirring, thereby improving the material utilization rate of the above-mentioned mixer. Furthermore, when the movable ring drives the scraper to move, the scraper can stir the inside of the mixing box, which helps to improve the stirring efficiency of the above-mentioned mixer for the material.

[0006] Preferably, the power mechanism includes a support plate arranged on the outside of the upper end of the mixing box, a drive motor arranged on the upper end of the support plate, a gear arranged at the output end of the drive motor, and a gear ring arranged on the outside of the movable ring, and the gear is meshed with the gear ring.

[0007] Through the above technical solution, when in use, the driving motor drives the gear to rotate circumferentially, and the gear drives the movable ring to rotate circumferentially through the gear ring engaged therewith, so as to clean and recycle the material attached to the inner wall of the mixing box.

[0008] Preferably, the scraper is arranged at an angle, and the extension direction of the inner side of the scraper is opposite to the rotation direction of the movable ring.

[0009] Through the above technical solution, the inclined scraper can not only be used to scrape off the material attached to the inner wall of the mixing box more effectively, but also can be used to guide the material on the side of the mixing box to move to the middle of the mixing box, thereby improving the mixing efficiency of the above mixer.

[0010] Preferably, a mounting seat is provided on the inner side of the movable ring opposite to the scraper, and a through hole is provided through the mounting seat from top to bottom. The scraper is slidably connected to the inner side of the through hole, and the outer wall of the scraper is in conflict with the inner wall of the through hole.

[0011] The above technical solution allows the scraper to be slidably connected to the mounting base via the through-hole, making assembly and disassembly relatively easy. Furthermore, as the scraper is moved upward, the mounting base can scrape off material adhering to the scraper surface, causing it to fall back into the mixing chamber, thereby improving the material utilization rate of the mixer.

[0012] Preferably, a mounting plate is provided at the upper end of the mounting seat, a positioning bolt is threadedly connected to the mounting plate, and a threaded section of the positioning bolt is tightly pressed against the scraper.

[0013] Through the above technical solution, the threaded section of the positioning bolt is tightly pressed against the scraper to limit the scraper so that the scraper is not prone to jumping up and down.

[0014] Preferably, a positioning boss is provided on the side wall of the scraper, and the threaded section of the positioning bolt is tightly pressed against the positioning boss.

[0015] Through the above technical solution, a positioning boss is provided on the side wall of the scraper to increase the contact area between the scraper and the positioning bolt, thereby improving the limiting stability of the scraper by the positioning bolt.

[0016] Preferably, a threaded hole is formed at the end of the positioning boss, and the threaded section of the positioning bolt is threadedly connected to the corresponding threaded hole.

[0017] Through the above technical solution, the threaded section of the positioning bolt is threadedly connected in the threaded hole, which can more effectively limit the scraper.

[0018] Preferably, two inclined guide surfaces are provided at the lower end of the mounting seat, the two inclined guide surfaces are respectively provided on both sides of the scraper, and the distance between the two inclined guide surfaces gradually increases from bottom to top.

[0019] Through the above technical solution, the distance between the two inclined guide surfaces gradually increases from bottom to top, which can guide the scraped material to fall into the inside of the mixing box, making it difficult for the scraped material to adhere to the lower end of the mounting seat.
